ISRAEL KINNEY, OF WINDSOR, ONTARIO, CANADA.

WRENCH AND PIPE-CUTTER.

SPECIFICATION forming part of Letters Patent No. 250,367, dated Becember6, 1881.

Application filed March 18, 1581.

To all whom it may concern Be it known that I, ISRAEL KINNEY, ofWindsor, county of Essex, Province of Ontario, Canada, have invented anew and useful Improvement in Pipe and Nut Wrenches and Pipe-Cutters;and I declare the following to be a full, clear, and exact descriptionof the same, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to the accompanyingdrawings, which form a part of this specification.

The object of my invention is to produce a wrench which shallautomatically adjust itself to grasp pipes or other articles ot'ditTerent sizes when turned in one direction, and become released whenturned in the opposite direction, for the purpose ot' taking a freshhold and to render such a wrench simple and strong in construction. Ithas the further object to provide such a wrench with a cutter orcutters, by which it may be converted into a cutting as well as awrenching tool.

In the accompanying drawings, Figure l is a wrench constructed accordingto my invention. Fig. 2 shows a modication thereof; and Fig. 3 is aperspective view of a wrench provided with cutters, by which it isenabled to be used as a pipe-cutting tool.

Referring to Fig. l, the letterA designates the wrench-handle, whichterminates at one end in a flat tapering tongue, A', having one of itsedges serrated, as shown at a.

The letters B and B indicate two strong jaws, which are connected by twostout parallel cross bars, C C, between which is an oblong space orslot, c, through which the tongue A is passed in order to brin gv itbetween the said jaws. The jaws B B preferably converge somewhat towardeach other from the crossbars, and the jaw B serves as an abutment orbrace for the tongue A when a pipe or other article is clasped betweenthe serrated edge of the tongue and the inner edge of the jaw B, andsaid jaw B opposes its entire inner edge equally to the tongue, so thatthere is simply a dead strain and no leverage exerted against said jaw.When a pipe is placed between the jaw B andthe serrated edge of thetongue A the handle is moved in the direction indicated by the arrowmarked upon it. The teeth of the tongue bite upon (Model.)

the object clasped, which object bears against the bar C, thus forcingthe jaws toward the wide end of the tongue and drawing saidtonguebetween thejaws to continually tighten its grasp by a wedge-likeaction as it slides along the jaw B. When the pipe or other object hasbeen turned as far as practicable, moving the handle in the oppositedirection bears it away from the jaw B and allows both jaws to slipsufficiently far toward the small end ot' the tongue to so loosen theobject as to permit the turning of the handle.

' In the modication shown in Fig. 2 the tongue A2 is curved edgewise,and the inner edge of the jaw B2 is correspondingly curved, so as to liesnugly against the outer edge ot' said tongue. The jaw B3 is curvedoutwardly, and may or may not be parallel with the inner edge of thejawB2.

In the modification shown in Fig. 3 the jaw B4 is concave, and isprovided with a rotary cutting-disk, d, Vwhich is pivoted in alongitudinal slot in said jaw, so that its cutting-edge will projecttoward the tongue A3, which is provided with the cutting-edge c oppositesaid rotary cutter. rIhe opposite edge ot1 the tongue is straight andplain, to bear against the full length of the inner edge ot1 the jaw B5,which is also straight. When this modilication is placed upon a pipe sothat said pipe lies between the cutting-edge c of the tongue and therotary cutter D, the handle is to be moved in the direction indicated bythe arrow, and at the same time pressed inwardly, so that it will bewedged against the object to be cut and rmly braced by the jaw B.

I am aware that wrench-bars have been pro. vided with double slidingjaws, and I lay no claim to such invention, broadly; but,

Having described my invention and eX- plained the operation thereof, Iclaim- 1. In a wrench, the combination, with the connected jaws havingtheir inner edges opposite each other, of the handle provided with atapering tongue, arranged to slide between said jaws and against theinner edge of one ot'I them, substantially as described.

2. In a wrench, the combination, with the jaws arranged opposite eachother and con nected by the bars or portion C, of the handle providedwith the tapering tongue passing IOO through said opening and having oneof its edges arranged to slide along the inner face of one of said jaws,substantially as described.

3. The combination of the jaws arranged opposite each other andconnected by the bars or portions C, of the rotary cutter d, pivoted inone of said jaws, and the handle A, provided with the tapering tonguepassing between said connecting bars or portions and arranged to slideagainst the jaw opposite the rotary cutro ter, substantially asdescribed.

In testimony whereof I sign this specification in the presence of twoWitnesses.
